Hintergrund der ErfindungBackground of the invention
1. Gebiet der Erfindung1. Field of the invention
Die vorliegende Erfindung bezieht sich auf ein lichtemittierendes Element, eine Beleuchtungsvorrichtung und deren Vorrichtungsrahmen und insbesondere auf ein lichtemittierendes Element, das Licht in vielen Richtungen zur Verfügung stellt, eine Beleuchtungsvorrichtung, die das lichtemittierende Element enthält, und einen Vorrichtungsrahmen der Beleuchtungsvorrichtung.The present invention relates to a light-emitting element, a lighting device and its device frame, and more particularly to a light-emitting element that provides light in many directions, a lighting device that includes the light-emitting element, and a device frame of the lighting device.
2. Beschreibung des Standes der Technik2. Description of the Related Art
Ein Lichtstrahl, der von einer Leuchtdiode (LED) emittiert wird, ist eine Art von gerichteter Lichtquelle, die verschieden ist von einer streuenden Lichtquelle einer herkömmlichen Glühlampe. Dementsprechend sind Anwendungen von LED eingeschränkt. Zum Beispiel kann die herkömmliche LED nicht die erforderten Lichteffekte für Beleuchtungsanwendungen im Innen- und Außenbereich zur Verfügung stellen oder es kann schwierig sein. Zusätzlich emittieren herkömmliche LED-Beleuchtungsvorrichtungen Lichtstrahlen von einer einzigen Seite und die Lichtleistung der herkömmlichen LED-Beleuchtungsvorrichtung ist dementsprechend relativ gering.A light beam emitted from a light emitting diode (LED) is a type of directional light source other than a diffusing light source of a conventional incandescent lamp. Accordingly, applications of LED are limited. For example, the conventional LED may not provide the required lighting effects for indoor and outdoor lighting applications, or it may be difficult. In addition, conventional LED lighting devices emit light beams from a single side and the light output of the conventional LED lighting device is accordingly relatively low.
